Azure Linux 3.0 Security Update: nodejs (CVE-2025-23165)
low Nessus Plugin ID 295900
Synopsis
The remote Azure Linux host is missing one or more security updates.Description
The version of nodejs installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-23165 advisory.- In Node.js, the `ReadFileUtf8` internal binding leaks memory due to a corrupted pointer in `uv_fs_s.file`:
a UTF-16 path buffer is allocated but subsequently overwritten when the file descriptor is set. This results in an unrecoverable memory leak on every call. Repeated use can cause unbounded memory growth, leading to a denial of service. Impact: * This vulnerability affects APIs relying on `ReadFileUtf8` on Node.js release lines: v20 and v22. (CVE-2025-23165)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
